DB measuring Options

[Legit94GT]

So when people compete on sound systems they measure the decibal (DB) level of the car to determine the winner. This got me thinking...


When they measure the DB in contest how exactly do they do it? is it just with a microphone in 1 place or a couple in 2 or 3 places in the car?



Has anybody here tested their system to see what kinda numbers they have gotten? if so where and how?

well basicky itssteve broke it down lol depending what mic you use will have a vast difference on your number the best mic out their is the TL use for all pro comps. but u can pick up a boom stick and talk into it and post a 155 lol i system is not done but i am going to run a wall with 4 15's with 750 watts each and i would guess i would post around a 150-151 with a lillte tuning the most common placement for the mic is on the dash in the middle stuck to the window if its in the kick it will read a little high than the dash never had it in the head rest or the port. but i know i have seen one 10 on a few hundred watts do 160 DB in the port lol and 180 DB's is the same as a TON of tnt going off from 15 feet away... 145 will kill a cat lol ya that was a bad day... RIP fluffy.. wow i still feel bad about that!
